TPS389012DSER

Texas Instruments · Supervisor And Reset ICs · WSON-6(1.5x1.5)

TPS389012DSER from Texas Instruments, in a WSON-6(1.5x1.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SENSE input Voltage monitoring input connected to the system voltage to be monitored; RESET asserts when SENSE falls below VITN and deasserts when SENSE rises above VITP (0 to 5.5 V).
2 GND power_in Ground reference.
3 MR input Manual reset input; driving this pin low causes RESET to go low (assert).
4 VDD power_in Supply voltage input from 1.5 V to 5.5 V; place a 0.1-µF ceramic capacitor close to this pin.
5 CT passive Capacitor timing pin; connect to a ground-referenced capacitor to set RESET delay time from 40 µs to 30 s per formula tPD(r) = CCT (µF) × 1.07 + 25 µs nominal.
6 RESET tri_state Open-drain output that asserts low when MR is driven low or SENSE falls below VITN; remains asserted for the programmed delay time after MR and SENSE return above VITP; requires 10 kΩ to 1 MΩ pullup resistor.
